Description

Technical Field

[0001] The utility model belongs to the technical field of emergency equipment, and particularly relates to a braking mechanism of a sliding bucket device, a sliding bucket device and emergency equipment. Background Art

[0002] For high-altitude ladder fire trucks, due to their high lifting height and limited load-bearing capacity of the ladder frame, it is not conducive to multiple people climbing at the same time; using the working bucket at the top of the ladder to directly perform telescopic amplitude change for rescue, the action speed is slow and the rescue efficiency is low. Therefore, high-altitude ladder fire trucks are mostly equipped with a fast sliding bucket for transporting people up and down. The sliding bucket device mainly consists of a sliding bucket frame, a ladder frame guide rail, a winch, a rope mechanism, a braking mechanism, and a roller mechanism. The sliding bucket device is placed at the guide rail of the upper chord of the ladder frame and can be driven by a steel wire rope to slide along the direction of the ladder frame through multiple rows of parallel rollers when in use. The appearance of the sliding bucket device can improve the efficiency and speed of high-altitude multi-person rescue, which is equivalent to setting up an "air elevator" between the ground and the fire site.

[0003] If the driving device of the sliding bucket device malfunctions or the lifting rope of the sliding bucket device breaks, it may cause the sliding bucket device to fall accidentally. Therefore, a braking mechanism needs to be set on the sliding bucket device so that the sliding bucket device can stop on the guide rail in case of an accident. The braking mechanisms in the prior art have poor stability. For example, some braking mechanisms drive the brake wheel to perform braking operations by means of flexible connectors such as steel wire ropes. The movement during braking of the braking mechanism is unstable, and the probability of braking failure is high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a braking mechanism of a sliding bucket device, a sliding bucket device and emergency equipment to solve the technical problem of unstable braking of the braking mechanism of the sliding bucket device in the prior art.

[0005] To achieve the above purpose, on the one hand, the utility model provides a braking mechanism of a sliding bucket device. The sliding bucket device further includes a lifting mechanism. The braking mechanism includes:

[0006] A mounting bracket;

[0007] A brake shaft rotatably arranged on the mounting bracket and drivingly connected to the lifting mechanism;

[0008] A brake member mounted on the outer periphery of the brake shaft and used to perform a braking operation after the brake shaft rotates;

[0009] An emergency component drivingly connected to the brake shaft and used to drive the brake shaft to rotate in an accidental state, where the accidental state is a state where the lifting mechanism is disconnected from the brake shaft, or the sliding bucket device is stuck in motion, or the lifting speed of the lifting mechanism exceeds the preset speed range.

[0010] In some embodiments, the sliding hopper device is slidably engaged with the sliding member. The emergency component includes a connecting crank and an elastic member. The first end of the connecting crank is sleeved on the outer periphery of the brake shaft and is coaxially and drivingly connected to the brake shaft, and the second end is pivotally connected to the elastic member. In an accidental state, the elastic tensile force of the elastic member drives the connecting crank to rotate, so that the braking mechanism enters a braking state, and the braking member frictionally brakes with the sliding member.

[0011] In some embodiments, the lifting mechanism includes a connecting block for drivingly connecting with the brake shaft. When the lifting mechanism is operating normally, the lifting mechanism drives the connecting block to rotate upward, and the connecting block drives the braking mechanism to maintain its normal state, and the braking member is separated from the sliding member.

[0012] In some embodiments, the brake shaft includes a first brake section, a connecting section, and a second brake section that are coaxially and sequentially connected. The connecting block is sleeved on the outer periphery of the connecting section, and brake members are sleeved on the outer peripheries of both the first brake section and the second brake section.

[0013] In some embodiments, the sliding hopper device includes a mounting frame, and the brake shaft passes through the mounting frame. The braking mechanism further includes: a first limiting rod, the two ends of which are respectively connected to the mounting frame, and the first limiting rod is arranged parallel and spaced above the brake shaft and is used to limit the upward rotation angle of the connecting block; a second limiting rod, the two ends of which are respectively connected to the mounting frame, and the second limiting rod is arranged parallel and spaced below the brake shaft and is used to limit the downward rotation angle of the connecting block.

[0014] In some embodiments, the mounting bracket includes: a mounting seat, which is detachably mounted in the mounting frame, and two mounting seats are respectively mounted at both ends of the brake shaft and are provided with a mounting space for accommodating the brake member; an end cover baffle, which is arranged on the side end face of the mounting seat and is rotatably connected to the brake shaft.

[0015] In some embodiments, the radial cross-section of the brake member is a fan-shaped structure, and the outer periphery of the brake member is provided with a friction end face that protrudes outward in an arc shape.

[0016] In some embodiments, the number of brake members is multiple, and the multiple brake members are arranged parallel and spaced along the axial direction of the brake shaft, and the multiple brake members are symmetrically distributed with the center of the brake shaft as the symmetry point.

[0017] The second aspect of the present utility model provides a sliding hopper device, including: a lifting mechanism; and the braking mechanism of the above-mentioned sliding hopper device.

[0018] The third aspect of the present utility model provides an emergency device, including: a sliding member; and the above-mentioned sliding hopper device.

[0019] In the above technical solution, the braking mechanism of the sliding bucket device includes a mounting bracket, a braking shaft, a braking member, and an emergency component. When the sliding bucket device is in an accidental state, the emergency component can pull to drive the braking shaft to rotate, and the rotation of the braking shaft can drive the braking member installed on the outer periphery of the braking shaft to perform a braking operation. By adopting the braking mechanism of the sliding bucket device described above, when the sliding bucket device is in an accidental state, the emergency component of the braking mechanism can promptly drive the braking shaft and the braking member to rotate, so that the sliding bucket device can stop immediately, preventing safety accidents such as the falling of the sliding bucket device.

It should be understood that the detailed implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0065] Next, the braking mechanism 10 of the sliding bucket device 100 according to the present utility model will be described with reference to the accompanying drawings.

[0066] As Figure 1 shown, it is a schematic structural diagram of the sliding bucket device 100 provided according to an embodiment of the present utility model; as Figure 2 shown, it is a schematic structural diagram of the braking mechanism 10 of the sliding bucket device 100 provided according to an embodiment of the present utility model; as Figure 3 shown, it is a schematic structural diagram of the cooperation between the braking mechanism 10 and the lifting mechanism 20 of the sliding bucket device 100 provided according to an embodiment of the present utility model; as Figure 4 shown, it is Figure 3 a partial enlarged schematic diagram of component A in

[0067] The sliding bucket device 100 is a device capable of sliding on a sliding member for transporting personnel and materials. In the embodiments of the present invention, the sliding bucket device 100 includes a braking mechanism 10 and a lifting mechanism 20. The braking mechanism 10 of the sliding bucket device 100 includes:

[0068] Mounting frame 11;

[0069] Braking shaft 12, rotatably arranged on the mounting frame 11 and drivingly connected to the lifting mechanism 20;

[0070] Braking member 13, installed on the outer periphery of the braking shaft 12 and used to perform a braking operation after the braking shaft 12 rotates;

[0071] Emergency component 14, drivingly connected to the braking shaft 12 and used to drive the braking shaft 12 to rotate in an accidental state, where the accidental state is a state in which the lifting mechanism 20 is disconnected from the braking shaft 12, or the sliding bucket device 100 is stuck in motion, or the lifting speed of the lifting mechanism 20 exceeds a preset speed range.

[0072] The mounting bracket 11 can be mounted on the sliding hopper device 100 and can be used to mount other components of the braking mechanism 10. The braking shaft 12 is rotatably arranged on the mounting bracket 11. The lifting mechanism 20 can drive the braking shaft 12 to move up and down so that the sliding hopper device 100 slides on the sliding member. The braking member 13 is mounted on the outer periphery of the braking shaft 12. When the braking shaft 12 rotates, it can drive the braking member 13 to frictionally brake with the sliding member. The emergency component 14 can pull the braking shaft 12 when the sliding hopper device 100 is in an accidental state, so that the braking shaft 12 rotates. The rotation of the braking shaft 12 can drive the braking member 13 to work, so that the braking member 13 frictionally brakes with the sliding member. In addition, one side of the sliding member is the braking member 13, and the other side is a clamping plate member (not shown in the figure) on the braking mechanism. When the braking member 13 frictionally contacts the sliding member, the clamping plate member can clamp and brake the sliding member together with the braking member 13. When the lifting mechanism 20 is disconnected from the braking shaft 12, the lifting mechanism 20 cannot continue to drive the braking shaft 12 to move up and down, and the sliding hopper device 100 will fall downward due to gravity. At this time, the emergency component 14 can pull the braking shaft 12 and drive the braking member 13 to brake. In addition, the jamming of the sliding hopper device 100 and the lifting speed of the lifting mechanism 20 exceeding the preset speed range are both accidental states, and the braking mechanism 10 needs to be activated to prevent safety accidents of the sliding hopper device 100.

[0073] By adopting the above braking mechanism 10 for the sliding hopper device 100, it is possible to automatically perform a braking operation when the sliding hopper device 100 is in an accidental state, and the mechanical transmission between the components of the braking mechanism 10 is simple, the torque transmission is stable, and the braking mechanism 10 can stably perform the braking operation.

[0074] In one embodiment, as Figure 2As shown, the sliding hopper device 100 is slidably engaged with the sliding member. The emergency component 14 includes a connecting crank 141 and an elastic member 142. The first end of the connecting crank 141 is sleeved on the outer periphery of the brake shaft 12 and is coaxially drivingly connected to the brake shaft 12, and the second end is pivotally connected to the elastic member 142. In an accidental state, the elastic tensile force of the elastic member 142 drives the connecting crank 141 to rotate, so that the braking mechanism 10 enters the braking state, and the braking member 13 frictionally brakes with the sliding member. When the sliding hopper device 100 is in an accidental state, the acting force between the lifting mechanism 20 and the brake shaft 12 is disconnected, and the connecting crank 141 can drive the brake shaft 12 to rotate under the elastic member, so that the brake wheel frictionally brakes with the sliding member. The emergency component 14 of the present application includes an elastic member 142, and the elastic member 142 has a tensile force. When the sliding hopper device 100 is in a normal state, the brake shaft 12 is subjected to the acting force of the lifting mechanism 20, and the elastic member 142 cannot pull the connecting crank 141. When the sliding hopper device 100 is in an accidental state (such as the lifting rope is disconnected), there is no acting force or a small acting force between the brake shaft 12 and the lifting mechanism 20, and the elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the braking member 13 to rotate, so that the braking member 13 can frictionally brake with the sliding member. With the above braking mechanism 10, when the sliding hopper device 100 is in an accidental state, the braking mechanism 10 can automatically perform a braking operation to prevent the sliding hopper device 100 from falling risk.

[0075] In the first specific embodiment, the accidental state is that the lifting rope is disconnected. When the lifting rope is disconnected, there is no acting force between the brake shaft 12 and the lifting mechanism 20, and the elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the braking member 13 to rotate, so that the braking member 13 can brake the sliding hopper device 100.

[0076] In the second specific embodiment, the accidental state is that the sliding hopper device 100 is stuck in motion. When the sliding hopper device 100 is descending, because the lifting mechanism 20 is connected to the braking mechanism through a flexible component, the lifting rope, when the sliding hopper device 100 is stuck in motion, there is no acting force between the lifting rope and the braking mechanism 10, and the elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the braking member 13 to rotate, so that the braking member 13 can brake the sliding hopper device 100.

[0077] In the third specific embodiment, the unexpected state is that the lifting speed of the lifting mechanism 20 exceeds the preset speed range. When the lifting speed exceeds the preset speed range, the sliding bucket device 100 cannot move smoothly, and the braking mechanism 20 performs a braking operation. For example, during the descent of the sliding bucket device 100, when the acceleration of the lifting mechanism 20 is too large, the force between the sliding bucket device 100 and the lifting mechanism 20 is small or there is no force. The elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the brake member 13 to rotate, so that the brake member 13 can brake the sliding bucket device 100.

[0078] In addition, there are other unexpected situations that can cause the elastic member 142 to pull the connecting crank 141, which will not be listed one by one here. For those of ordinary skill in the art, the specific meanings of the above unexpected situations in the present utility model can be understood according to specific circumstances.

[0079] In one embodiment, as Figure 3 shown, the lifting mechanism 20 includes a connecting block 21 for drivingly connecting with the brake shaft 12. When the lifting mechanism 20 is operating normally, the lifting mechanism 20 drives the connecting block 21 to rotate upward, and the connecting block 21 drives the braking mechanism 10 to maintain its normal state, and the brake member 13 is separated from the sliding member. The connecting block 21 of the lifting mechanism 20 is drivingly connected with the brake shaft 12. When the lifting mechanism 20 is operating normally, the lifting mechanism 20 transmits an upward tensile force, and the connecting block 21 can transmit a torsional force opposite to the acting force of the connecting crank 141 to the brake shaft 12 when receiving the upward tensile force, so that the brake shaft 12 remains stationary. When the brake shaft 12 does not rotate, the brake member 13 is separated from the sliding member, and the sliding bucket device 100 can slide up and down along the sliding member.

[0080] In one embodiment, as Figure 2 shown, the brake shaft 12 includes a first brake section 121, a connecting section 122, and a second brake section 123 that are coaxially connected in sequence. The connecting block 21 is sleeved on the outer periphery of the connecting section 122, and brake members 13 are sleeved on the outer peripheries of both the first brake section 121 and the second brake section 123. The first brake section 121 and the second brake section 123 are coaxially connected to both sides of the connecting section 122. When the lifting mechanism 20 pulls the brake shaft 12, the position where the force is applied is at the central position of the brake shaft 12, which can enable the lifting and sliding bucket device 100 to slide up and down more smoothly. Brake members 13 are sleeved on both the first brake section 121 and the second brake section 123. When a braking operation needs to be performed, the brake members 13 on the first brake section 121 and the second brake section 123 simultaneously frictionally brake with the sliding member, which can make the braking of the sliding bucket device 100 more stable.

[0081] In one embodiment, as Figure 3As shown, the sliding bucket device 100 includes a mounting frame 30. The brake shaft 12 passes through the mounting frame 30. The brake mechanism 10 further includes: a first limiting rod 15, with both ends of the first limiting rod 15 connected to the mounting frame 30 respectively. The first limiting rod 15 is arranged parallel and at intervals above the brake shaft 12 and is used to limit the upward rotation angle of the connecting block 21; a second limiting rod 16, with both ends of the second limiting rod 16 connected to the mounting frame 30 respectively. The second limiting rod 16 is arranged parallel and at intervals below the brake shaft 12 and is used to limit the downward rotation angle of the connecting block 21. The connecting block 21 can rotate upward under the action of the lifting mechanism 20. When the elastic member 142 pulls the brake shaft 12 to rotate, the connecting block 21 will be forced to rotate downward. However, the force conditions of the connecting block 21 are different, and the swinging areas of the connecting block 21 are different. When the connecting block 21 swings towards the sliding member, it is easy to cause friction and collision with other components, and it can also prevent the connecting block 21 from resetting. Therefore, it is necessary to limit the swinging angle of the connecting block 21. The brake mechanism 10 of the embodiment of the present utility model includes a first limiting rod 15 and a second limiting rod 16. The first limiting rod 15 and the second limiting rod 16 can respectively limit the upward rotation angle and the downward rotation angle of the connecting block 21, preventing the connecting block 21 from being forced to interfere and collide with the sliding member.

[0082] In one embodiment, as Figure 3 and Figure 4 shown, the mounting bracket 11 includes: a mounting seat 111, detachably mounted in the mounting frame 30. Two mounting seats 111 are respectively mounted at both ends of the brake shaft 12 and are provided with a mounting space for accommodating the brake member 13; an end cover baffle 112, arranged on the side end face of the mounting seat 111 and rotatably connected to the brake shaft 12. The mounting seat 111 can be used to mount the brake member 13, and the end cover baffle 112 can be used to mount the first brake section 121 or the second brake section 123 of the brake member 13. When installing the brake mechanism 10, the mounting seat 111 can be installed first, then the brake member 13 is installed in the mounting space inside the mounting seat 111, and finally, the end cover baffle 112 is installed on the mounting seat 111. The first brake section 121 or the second brake section 123 passes through the brake member 13 and is rotatably connected to the end cover baffle 112 to complete the installation of the brake module. Subsequently, the connection section 122 of the brake module and the brake shaft 12 are coaxially connected to complete the assembly of the brake mechanism 10. By using the above brake mechanism 10, the brake mechanism 10 can be assembled modularly, simplifying the assembly steps of the brake mechanism 10 and improving the assembly efficiency.

[0083] In one embodiment, as Figure 3 and Figure 4As shown, the radial cross-section of the brake member 13 is a sector structure, and the outer periphery of the brake member 13 is provided with a friction end face that protrudes outward in an arc shape (not shown in the figure). When the brake member 13 rotates, the friction end face of the brake member 13 faces the sliding member, and the sliding bucket device 100 is braked and stopped under force. In a specific embodiment, the friction end face is arranged at the large head end of the sector structure. When the large head end faces the sliding member, the brake member 13 and the sliding member rub against each other; when the small head end faces the sliding member, the brake member 13 and the sliding member are spaced apart from each other.

[0084] In one embodiment, the number of the brake members 13 is multiple. The multiple brake members 13 are arranged in parallel at intervals along the axial direction of the brake shaft 12, and the multiple brake members 13 are symmetrically distributed with the center of the brake shaft 12 as the symmetry point. The sliding bucket device 100 can usually move on multiple sliding members, and the spacing widths of the guide rails on different sliding members are different. Therefore, the present utility model provides multiple brake members 13 so that the brake members 13 can cooperate with guide rails of different widths to make the braking more timely and efficient. Among them, the brake member 13 can be selected in structural forms such as a brake cam, a brake block, etc.

[0085] With the brake mechanism 10 of the sliding bucket device 100 as described above, when the sliding bucket device 100 is in an accidental state, the elastic member 142 on the brake mechanism 10 can pull the connecting crank 141 to rotate in the direction of the elastic member 142, so that the brake shaft 12 rotates. The rotation of the brake shaft 12 can drive the brake member 13 to rotate. The outer periphery of the brake member 13 is provided with a friction end face that protrudes outward. The friction between the friction end face and the sliding member can brake the sliding bucket device 100 and prevent the sliding bucket device 100 from falling at a high altitude. With the brake mechanism 10 of the sliding bucket device 100 as described above, the torque transmission between each component is stable, the movement speed is fast, and the sliding bucket device 100 can be braked stably.

[0086] In one embodiment, a sliding bucket device 100 is provided, including: a lifting mechanism 20; and the brake mechanism 10 of the sliding bucket device 100 as described above.

[0087] In one embodiment, as Figure 5 shown, it is a schematic structural diagram of the bottom plate support frame 50 provided according to an embodiment of the present utility model. The sliding bucket device 100 moves relative to the sliding member. The sliding bucket device 100 further includes: a vertical plate support frame 40, extending vertically and close to one side of the sliding member; a bottom plate support frame 50, with the first end rotatably connected to the vertical plate support frame 40; a telescopic assembly 60, with both ends of the telescopic assembly 60 respectively hinged to the vertical plate support frame 40 and the bottom plate support frame 50. The telescopic assembly 60 is used to assist the second end of the bottom plate support frame 50 to swing towards or away from the sliding member.

[0088] The vertical plate support frame 40 can be used to install the vertical plate of the sliding hopper device 100, and the bottom plate support frame 50 can be used to install the bottom plate of the sliding hopper device 100. The vertical plate support frame 40 extends vertically and is arranged on the side facing the sliding member. The bottom plate support frame 50 is rotatably connected to the vertical plate support frame 40. After the second end of the bottom plate support frame 50 rotates towards the vertical plate support frame 40, the space of the sliding hopper device 100 is reduced, which is convenient for transportation.

[0089] The sliding hopper device 100 provided by the embodiment of the present invention includes a telescopic assembly 60. Both ends of the telescopic assembly 60 are respectively hinged to the vertical plate support frame 40 and the bottom plate support frame 50, and the telescopic assembly 60 has a driving force axially downward. When the bottom plate support frame 50 of the sliding hopper device 100 is folded upward, the telescopic assembly 60 provides assistance to make it easier for the operator to fold the bottom plate support frame 50. When the bottom plate support frame 50 of the sliding hopper device 100 is unfolded downward, the telescopic assembly 60 can also provide assistance to make it easier for the operator to unfold the bottom plate support frame 50.

[0090] In one embodiment, as Figure 6 shown, it is a partial enlarged schematic view of the sliding hopper device 100 when it is unfolded according to the embodiment of the present invention. As Figure 7 shown, it is a partial enlarged schematic view of the sliding hopper device 100 when it is folded according to the embodiment of the present invention. The sliding member extends vertically. The hinge point of the telescopic assembly 60 and the bottom plate support frame 50 is the first hinge point, and the hinge point of the bottom plate support frame 50 and the vertical plate support frame 40 is the second hinge point; when the second end of the bottom plate support frame 50 is far from the sliding member, the first distance between the first hinge point and the sliding member is less than the second distance between the second hinge point and the sliding member. The sliding member has a driving force axially downward. When the operator lifts the bottom plate support frame 50 manually, the bottom plate support frame 50 rotates counterclockwise around the second hinge point, and the acting force of the telescopic assembly 60 on the bottom plate support frame 50 is also a counterclockwise torsional force. Therefore, the telescopic assembly 60 can provide assistance when the bottom plate support frame 50 is folded upward, so that the operator can more easily lift the sliding hopper device 100. When the second end of the bottom plate support frame 50 is close to the sliding member, the first distance is greater than the second distance. When the bottom plate support frame 50 is folded, the second end of the bottom plate support frame 50 is close to the sliding member, and the distance between the first hinge point and the sliding member is greater than the distance between the second hinge point and the sliding member. When the sliding hopper device 100 is unfolded, the bottom plate support frame 50 rotates clockwise around the second hinge point, and the sliding member has a driving force axially downward, which can assist the bottom plate support frame 50 to rotate clockwise and unfold.

[0091] In one embodiment, as Figure 5As shown in the figure, the bottom plate support frame 50 includes: a bottom frame portion 51; and a plurality of rotating portions 52 provided on one side of the bottom frame portion 51 close to the sliding member. One end of the rotating portion 52 facing away from the bottom frame portion 51 is hinged to the vertical plate support frame 40, and the hinge point is the second hinge point; and a boosting support portion 53. The other end of the boosting support portion 53 is hinged to the telescopic assembly 60, and the hinge point is the first hinge point. Among them, the plurality of rotating portions 52 and the boosting support portions 53 are arranged at staggered intervals along the length direction of the bottom frame portion 51. The bottom frame portion 51 of the bottom plate support frame 50 can be used to install the bottom plate, and can also install a plurality of rotating portions 52 and a plurality of boosting support portions 53. The rotating portion 52 is hinged to the vertical plate support frame 40. When the bottom plate support frame 50 rotates, the second hinge point where the rotating portion 52 is hinged to the vertical plate support frame 40 remains stationary. The boosting support portion 53 is hinged to the telescopic assembly 60. The telescopic assembly 60 can transmit the driving force it has to the bottom frame portion 51 through the boosting support portion 53, so as to facilitate the upward folding or downward unfolding of the bottom plate support frame 50.

[0092] In one embodiment, as Figure 5 shown, the rotating portion 52 includes a first hinge section 522 and a first welding section 521. One end of the first welding section 521 is welded to the top surface of the bottom frame portion 51. The other end of the first hinge section 522 is arc-transitionally connected to the first welding section 521.
